The number line is a closed circle because the circle at the ends are not shaded in. A closed circle to the right means greater than. (>) A closed circle to the left means less than. (<)
The length of each piece is 0.1 yard.
<u>Step-by-step explanation:</u>
The length of the pipe is 
yard.
The pipe is cut into 5 equal pieces.
We have to find the length of the each piece.
The length of the each piece is calculated by dividing the pipe's initial length(L) by the the number of pieces(N).
Length of the each piece = 
.

. ( 5 is also written as 
⇒ 
.)

= 0.1 yard.
Length of the each piece = 0.1 yard.

Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
